Cerablanket Kaowool blanket cut length diagram

We sell cut lengths by the running or linear foot in continuous lengths.
That is 1 foot = 12" x 24". 2 feet = 24" x 24", 3 feet = 24" x 36" . . .

NOTE: It is cheaper to purchase a Full 25 foot Carton of 1" material than two 10 foot cut lengths.

While we specialize in supplying small quantities we can also provide truck load quantities anywhere in North America.

Please do not confuse our prices with others who sell at similar prices but by the square foot.  We have a significant price breaks at 5 feet, 10 feet and for full cartons with quantity discounts.

ABSOLUTELY NO RETURNS on cut materials

NOTE: Max-Wool is replacing Kaowool Cerablanket at the same price due to supply issues.

Max-Wool HPS - 2,300°F / 1,260°C is the same as the original asbestos replacement material invented by Babcock and Wilcox and is similar to Inswool and other competing products. Max-Wool blanket l is commonly used to insulate high temperature furnaces, process piping and to build forges and kilns.

The great advantage of Max-Wool over other refractories is its very low density and easy of handling. The density of Max-Wool is approximately the same a dense fiber glass blanket and less than balsa wood. The blanket is easy to cut with scissors or a utility knife making it possible to cut accurate shapes. This ease of handling quickly offsets the cost difference compared to castable or refractory brick while providing a much higher insulating value.

Max-Wool (kaowool) is commonly used to construct blacksmiths' forges and is often left uncoated. However, all refractory blanket should be coated with a hard refractory to protect it from physical damage and creating airborne refractory dust. ITC-100 is commonly used but is not 100% resistant to poking with sharp objects. A coating of refractory cement or patching compound such as Grefpatch or ITC-200 is recommended in hard use areas followed by another coating of ITC-100.

Max-Wool HPS comes in cartons of 50 square feet of 1" thick 24" wide rolled material, and 100 Square feet of 1/2" thick 24" wide material. We sell cut lengths starting at one foot (two square feet), partial cartons and full cartons.

NOTE!  Weight reported on the invoice is shipping weight including UPS oversize (dimensional weight) for full cartons.
